This article briefly introduces the phenomena of ki- energy to the Western readers who are not familiar with them, by relying on Yuasa Yasuo's conceptual scheme. Ki- energy has traditionally been an intense thematic focus of various East-Asian fields of human endeavours such as acupuncture medicine, martial arts and meditational training. The article articulates some of the salient features of this energy as it is understood in these fields, while incorporating knowledge of contemporary scientific research on them. It is written (...) with a view to stimulating further research on it, as it carries important implications for addressing many of the issues we face today. (shrink)
